Getting On-Screen Keyboard "Paste" button to work

I THINK I've got it.  I admit I don't understand the OSK code _at all_.

   * Text & Label Tool Improvements:
     -------------------------------
     + WIP It is now possible to paste text from the copy/paste clipboard
       into Tux Paint.  If text goes beyond the right of the canvas,
       a new line is created.  If text goes beyond the bottom of the
       canvas, the text is truncated there.
-      - WIP: Add a "paste" button to the On Screen Keyboards
       - TODO: Improve word-wrapping (word-based, not character)
       - TODO: Mention the feature in documentation
       Closes https://sourceforge.net/p/tuxpaint/feature-requests/95/
